BD Backend: Volume creation support
A new parameter type is added to volume create command. To use BD xlator one has to specify following argument in addition to normal volume create device vg brick:<VG-NAME> for example, $ gluster volume create lv_volume device vg host:/vg1 Changes from previous version * New type 'backend' added to volinfo structure to differentiate between posix and bd xlator * Most of the volume related commands are updated to handle BD xlator, like add-brick, heal-brick etc refuse to work when volume is BD xlator type * Only one VG (ie brick) can be specified for BD xlator during volume creation * volume info shows VG info if its of type BD xlator BUG: 805138 Change-Id: I0ff90aca04840c71f364fabb0ab43ce33f9278ce Signed-off-by: M.
